Precision Twist Drill 010027 Hss Jobber Drill Bit 27/64 in

Product Description

The PRECISION TWIST DRILL 010027 is a high-speed steel (HSS) jobber-series drill bit built for drilling into hard surfaces where heat and mechanical stress are constant factors. With a 27/64 inch tip diameter and an overall length of 5-3/8 inches, this bit delivers a 4 inch depth of cut in a compact jobber-length profile. HSS construction maintains hardness at elevated cutting temperatures, making it a reliable choice for production and maintenance drilling across metal, wood, and composite materials. Licensed tradespeople and industrial maintenance technicians are the primary users of this tool.

This drill bit fits standard drilling applications in residential, commercial, and light industrial settings. The jobber-length format is the most common sizing for general-purpose work, compatible with both handheld drills and drill press setups. The 27/64 inch diameter is frequently used for clearance holes and tapping pre-drill operations on larger fastener sizes. Its balanced proportions make it straightforward to use in benchtop and on-site conditions alike.

Key Features

• High-speed steel (HSS) construction resists heat buildup during aggressive cutting
• Jobber-series length provides the versatility needed for most standard drilling tasks
• 27/64 inch tip diameter suitable for clearance and tap-pilot applications
• 4 inch depth of cut accommodates typical material thicknesses encountered in trade work
• Overall length of 5-3/8 inches fits standard chuck and drill press configurations

Compatibility

Designed as a general-purpose jobber-length HSS drill bit suitable for use in standard three-jaw chucks on handheld drills and drill presses accepting 27/64 inch shank sizes.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the chuck key is removed prior to powering the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to reduce heat buildup and extend bit life. Always wear eye protection and ensure the workpiece is clamped or fixed to prevent rotation. Inspect the cutting edges for wear before each use and replace the bit when dulling is evident to maintain hole accuracy.
